A Non-asbestos Sheet is a high-performance sealing and gasketing material engineered to replace traditional asbestos-based products. As global health and safety regulations phased out asbestos due to its carcinogenic properties, advanced composite materials were developed to offer equal or superior performance without the associated health risks. Kaxite Sealing is at the forefront of this innovation, producing premium non-asbestos sheets that deliver exceptional durability, thermal stability, and chemical resistance for demanding industrial applications.
Kaxite Sealing offers a range of non-asbestos sheets, each formulated for specific service conditions. Below are the detailed parameters for our standard series.

Q: What exactly does "non-asbestos" mean? Is it 100% safe?
A: "Non-asbestos" means the material is manufactured without using any asbestos fibers. Instead, it uses safer, synthetic or organic fibers like aramid, glass, cellulose, or carbon. Products from Kaxite Sealing are rigorously tested and certified to be completely asbestos-free, making them safe for handling, cutting, and installation without the health risks of lung diseases associated with asbestos.
Q: Can a non-asbestos sheet truly match the performance of old asbestos gaskets?
A: Yes, absolutely. Modern non-asbestos sheets like those from Kaxite Sealing are not just substitutes; they are technological upgrades. They are engineered to meet or exceed the sealing performance, temperature resistance, and durability of traditional asbestos materials. Advancements in fiber technology and binder systems often result in better compressibility, recovery, and chemical compatibility.
Q: How do I choose the right grade of non-asbestos sheet for my application?
A> Selection depends on the specific service conditions. You must consider the medium (steam, oil, chemical), temperature range, pressure, and flange type. Refer to our technical table above: use Standard (KAX-NAS 1000) for general purposes, High-Temp (KAX-NAS 2000) for heat applications, Chemical Resistant (KAX-NAS 3000) for aggressive fluids, and Compressed (KAX-NAS 4000) for high-pressure flanges. Kaxite Sealing's technical team can provide specific recommendations.
Q: Are there specific storage or handling requirements for these sheets?
A> Non-asbestos sheets should be stored in a cool, dry place away from direct sunlight, extreme heat, and moisture. Store them flat to prevent curling or bending. While safer than asbestos, it is still good practice to use standard workshop safety measures when cutting or sanding—such as dust extraction or a simple dust mask—to minimize inhalation of any non-toxic particulate matter.
Q: How do I install a gasket made from a non-asbestos sheet correctly?
A> Proper installation is key to performance. Ensure flange surfaces are clean, flat, and free of old gasket material. Cut the gasket accurately to size—it should fit inside the bolt holes without protruding into the pipe bore. Use a suitable gasket cutting tool or CNC for precision. Apply a thin, even layer of gasket adhesive if required (check compatibility). Tighten bolts evenly in a crisscross pattern to the manufacturer's specified torque values to achieve a uniform seal.
Q: Does Kaxite Sealing offer custom-sized sheets or pre-cut gaskets?
A> Yes. While we supply standard-sized sheets, Kaxite Sealing provides full customization. We can manufacture sheets to specific dimensions, thicknesses, and even with pre-cut gaskets (die-cut, laser-cut, or water-jet cut) based on your technical drawings or CAD files. This ensures a perfect fit and reduces on-site fabrication time and waste.
Q: What certifications do Kaxite Sealing non-asbestos sheets hold?
A> Kaxite Sealing products are developed in compliance with major international standards. They are tested and certified to meet specifications such as ASTM F1315, DIN 3754, and JIS B 2403. Our quality management system is ISO 9001 certified, and our materials are compliant with RoHS and REACH regulations, guaranteeing their safety and performance for global markets.
